I simply pulled the old non-gfci circuit that ran to my detached garage out
of the panel, then ran a short line to a surface mounted box a few feet from
the panel with a gfci outlet. I then pulled the garage line into that so now
I have a much needed outlet near my panel and the garage and underground
line leading out to it is protected.

Did the same for an old bathroom circuit that was not protected - but in
this case I was able to put the gfci outlet in an other area of the basement
where there was no outlet so now I have one and the bath is protected.

I want to add GFCI to a pool light circuit. I traced the circuit to a
Square D XO subpanel. The XO series breaker box is obsolete and the only
breakers I can find are regular used ones (no GFCI breakers for XO). It
would be a huge job to replace the entire subpanel just for this circuit,
because it contains a maze of other old circuits. Is there any GFCI
breaker that will plug into the XO box? Is there a GFCI device that I can
connect to the junction box in the pool equipment room? Maybe a simple one
switch circuit breaker box that can connect through a knockout.. something
that would install without turning it into a huge construction job?
